Good taste is the starting point. For a UK store, the designer also has to work within a few rules that shape the layout.
Cookie banners. The ICO expects rejecting non-essential cookies to be as easy as accepting them, so a banner with a bright Accept button and a hidden Reject link is a compliance problem, not just a design choice.
Accessibility for EU customers. Since 28 June 2025, the European Accessibility Act covers online shops selling to consumers in the EU, including UK sellers. Microenterprises (fewer than 10 staff and annual turnover or balance sheet of โฌ2 million or less) are exempt. Contrast, focus states, alt text and keyboard navigation are design decisions; see our Shopify accessibility guide.
Prices with VAT. UK shoppers see VAT-inclusive prices. If you also sell to the EU, product cards and carts need room for prices that change by market.
